2006 1-foot Orthophotography (National Forest) – LARIAC

Coverage

***NOTE***The imagery is held under license from InfoTech International, and cannot be publicly released. 

Natural color, leaf-off, 1-foot high-resolution, high-accuracy orthorectified aerial imagery, acquired by the Los Angeles Regional Imagery Consortium (LARIAC) in early 2006.  This imagery covers  the National Forest areas of the County, approximately 1,056 square miles, and is a separate dataset.  The urban/suburban areas of the County in mainland (approximately 2,898 square miles) and Santa Catalina Island are covered by a 4-inch dataset.    Information about the 4-inch data is available in another part of the Data Portal.

This dataset meets or exceeds ASPRS (American Society for Photogrammetry and Remote Sensing) 1:200 scale mapping.  Accuracy is within +/- 2 feet of true location with 95% confidence.

Detailed product information is contained in the LARIAC Product Guide.

We highly recommend that you visit the LARIAC Project Website to find a rich source of information about the data and the LARIAC Program.  The site includes project documents, full FGDC compliant metadata, data downloads of related GIS used to complete the project, sub-licensing information, sample imagery and data, and information about the 2006 acquisition.

GIS Data showing flight-date information is available from the site, and elsewhere in the LA County GIS Data Portal.

The imagery is held under license from InfoTech International, and cannot be publicly released.  Government entities are eligible to join the LARIAC Program to access the data.  Private entities may contact LA County directly to purchase selected parts of the data.

 

About LARIAC

The Los Angeles Region Imagery Acquisition Consortium (LARIAC) Program is a collaborative acquisition program for digital aerial imagery data which has included the participation of 10 County departments, 30 municipalities, and four other public agencies.

1-foot/4-inch comparison

The Consortium is a model for regional cooperation that improves the quality, access, and cost-effectiveness of high resolution digital aerial imagery. Knowledge transfer is increased through consortium program meetings, user groups, and various workshops that have been established in conjunction with the project. The imagery acquired will enable all participating jurisdictions to leverage this key geographic information asset for numerous decision support and business applications, thereby facilitating the effective and efficient delivery of services.
